Literally, a "bag of
ho." A hobag is a person (usually female) who is
slutty, all over everyone she meets, or just plain annoying.
Another form of this word is the less-commonly used "
whorebag."
Guy: Man,
Melissa is all over that guy! She never even met him before!
Guy2: Yeah, dude. She is such a hobag!

Girl: Jane is such a
catty person, the hobag.
